Anyone unfamiliar with the Aire and Candeeiros mountain ranges might think that their elevations of 577 and 613 meters respectively would be nothing extraordinary in terms of landscape. However, this massif, stretching between Ourém in the north and Rio Maior in the south, is a veritable kingdom of (limestone) stone. Besides the two mountain ranges that give it its name, it includes the Serra de Mendiga, the Santo António Plateau, and part of the São Mamede Plateau. Also, noteworthy is the Dinosaur Footprints Natural Monument.

Located in an old wine press, this museum has been open to the public since 1993 and aims to showcase utensils, clothing, and everything that was characteristic of the rural heritage of this region.

The Rio Maior Salt Pans Ecomuseum is located about 3 km from the city center and nestled in a valley at the foot of the Serra dos Candeeiros, in the heart of the Serras de Aire e Candeeiros Natural Park. Classified as a Property of Public Interest since December 1997, these salt pans are the only inland salt pans in Portugal. The first reference to their existence dates back to 1177, but rock salt is thought to have been used since prehistoric times. Surrounded by vineyards and farmland, they are considered a natural wonder, as the sea is 30 km …

Located 17 kilometers from Rio Maior, the area's main feature is its extensive valley with rock salt flats. Architectural highlights include the Nossa Senhora do Rosário parish church, the pillory, the former Town Hall, now the Azambujeira Regional Museum, and the single-arch stone fountain bridge built during the reign of Queen Maria. Local crafts include blankets, pottery, and wooden clubs.

Located in a valley adjacent to the Serra dos Candeeiros, it is bathed by a stream that originates in the picturesque site of Olhos de Água. Here, you'll find beautiful natural caves and rooms with stalactites, calcite crystals, and remains of bones. Among the architectural heritage, a megalithic dolmen (Property of Public Interest) attached to the church stands out, containing a fifteenth-century sculpture, and traces of Roman times, evident in the ruins of a communal oven.

These are the only natural salt pans in Portugal. Located 30 kilometers from the sea, they have 400 tanks, from which salt is extracted from a depth of about 10 meters. Between May and September, the salt is collected, after the water (which contains about 200 to 300 grams of salt) is collected and evaporated after a week.

The name of this manor house derives from the fact that Dom Miguel spent the night here before the Battle of Almoster. This manor house is notable for its ceilings painted with royal coats of arms, the chapel-oratory with a Baroque façade, and the porch leading to the house. The lower floor was occupied by services, while the upper floor housed the residence.

The architecture is religious in nature, consisting of a vaulted chancel and a nave, the latter with two side altars. The sacristy preserves a Baroque lavatory. Another highlight is the baptismal font, brought from the main church, which is housed in a chapel under the tribune, next to the Chapel of Senhor dos Passos.

La villa romaine de Rio Maior a été découverte en 1983. Les fouilles, commencées en 1995, ont livré une quantité importante de matériel. Un ensemble de panneaux de mosaïque a été découvert, dont les couleurs et le motif dateraient du IIe ou IIIe siècle apr. J.-C.

This is one of three megalithic monuments in Portugal. Belonging to the Alcobertas Parish Church, this funerary dolmen consists of a chamber and a corridor formed by large pillars. Notable features include the tile covering and stone altar.
